The wife of an elder ('anointed', to boot) was obsessed with this subject. When you talked to her you could almost see the tiny pinwheels spinning in her eyes. She made it her official job to get the word out that we must not buy anything used, clothes, furnishings, etc. because it could be possesed by demons. This made it kind of tough if you were raising kids on a janitors income.
Our Kingdom Hall was built on land donated by a elderly witness couple. They lived next door in beautiful old house. One day, when Sister Elder ,
(who lived in a trailer) was visiting Sister Elderly, she began to fix on the lovely, matching, ceramic lamps at each end of the sofa. She decided they didn't look right, in fact, as she looked at them she began to see a face in the abstract design! She explained to Sister Elderly what they had to do. Yep, they took those lamps out to the garage and beat then to death with hammers! When Brother Elderly got home he hit the roof. He remembered laying out $1200.00 for them when they were purchased many years before.
The kooky thing about this nutcase was that she went through a phase of being obsessed with the practice of diagnosing physical ailments by looking at the iris of the eyes. After the meeting she would have people in the back of the hall looking in their eyes with a penlight. Thank God she never saw any faces in somebodys eye!
